Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To obtain an ND filter having density distribution by irradiating a plastic film containing an org. dye with higher energy light while the light amt. is partially changed. SOLUTION: An org. dye is kneaded in a plastic film and the film is partially irradiated with high energy light so that the org. dye in the irradiated part is decomposed to decrease the density compared to the part not irradiated. Thus, a gradation ND filter having density distribution is obtd. In this method, an org. dye which fades by irradiation of light is used. It is preferable to select such an org. dye and a base plastic material that the film before fading shows flat spectral characteristics and has ND and that the film after irradiation of light also shows flat spectral characteristics. As for the light source for irradiation, a light source of extremely high energy compared to irradiation of normal sun rays is used. As for the org. dye, 16 compds. from No.1 to No.16 shown in the example can be used.

SOLUTION: The density of straight-chain low-density polyethylene is set in the range of 0.930-0.950g/cm<3> , and when the density is less than 0.930g/cm<3> , sometimes heat resistance is lowered to generate the fusion bonding of the inner face of a sealant film. while when the density is beyond 0.950g/m<3> , the film gets too hard to be likely to lower the impact resistance.  The retort sealant film having a rough surface is heat sealed, and the roughness is different when a material to be used, the required heat resistance temperature and the like are different, and the ten-points average roughness is preferably in the range of 8-50μm, while when the ten-points average roughness is less than 8μm, heat resistance is lowered, and sometimes the fusion bonding of the inner face of the sealant films is generated, and when the ten-points average roughness is beyond 50μm, sometimes heat sealing properties are lowered.

IPC: B67D7/32
Filed: 1987-10-02
Abstract: PURPOSE: To accurately detect the oil leakage by preventing the increase of volume caused by the unfastening of an oil supply hose, by detecting the oil leakage during the time when an oil supply nozzle is stopped at a ceiling position or an intermediate position. CONSTITUTION: For example, when an oil supply nozzle 9 is lowered to an intermediate position B, the rotation of a reel motor 8 is stopped by the operation of a controller 15 on the basis of a detection signal from a nozzle position detector 10, and a pump motor 11 starts its rotation simultaneously with the stop of the oil supply nozzle 9 at the intermediate position B. It is not judged as the oil leakage even when the flow of oil is detected during the time T1 after the start of the rotation of the pump motor 11 because it is judged that it is caused by the pump pressure, but when the oil flow exists in an oil supply pipe 1 after the passage of the time T1 , and a pulse signal is transmitted from a flow pulse transmitter 21, this pulse signal is transmitted to the controller 15, and the pulse number is counted.  When the pulse number (n) becomes N, the generation of the oil leakage is judged, so that the judgement is output to an alarm 14 from the controller 15 to inform the generation of the oil leakage, and the oil supply device is simultaneously stopped. The oil leakage position is searched to be repaired.

Title: Multiprocessor scheduling method
Inventor: KAMIWAKI TADASHI
IPC: G06F9/50
Filed: 1989-09-28
Abstract: PURPOSE:To improve the performance of cache memory and to reduce the load of a bus by controlling the processes turned into groups and carrying out the processes in the same group via the same processor. CONSTITUTION:When the processes having a large quantity of shared data are carried out by different processors 13-1 - 13-3, the communication is frequently produced to secure the coincidence of caches. As a result, the cache performance is deteriorated. In this respect, such processes 12-1 - 12-8 are turned into the groups 15-1 - 15-3 and carried out by the same processors 13-1 - 13-3. Thus no communication is required for coincidence of caches. Then the groups are carried out by a specific one of processors 13-1 - 13-3 and therefore the processes which are left unexecuted for a fixed time or longer can be carried out by any of processors 13-1 - 13-3 so that the load is not biased among the processors 13-1 - 13-3. As a result, the performance of a cache memory is improved and the load can be scattered.

Abstract: PURPOSE:To provide a printer which efficiently controls the warmup of a fixing device. CONSTITUTION:An exhaust opening 3 is provided with an exhaust-window opening/closing mechanism 4, and also a fixing device 5 is provided with a temperature sensor 7. A printer is provided with a main control part 11 which drives and controls an air cooling fan 2, the exhaust-window opening/closing mechanism 4, the fixing device 5, and a fixing heater 6 independently based on the output of the temperature sensor 7; and a warmup-mode setting function whereby, when the heater 6 is energized, the main control part 11 controls the air cooling fan 2 so that it is stopped until the fixing temperature of the fixing device 11 reaches a specific temperature and also controls the exhaust- window opening/closing mechanism 4 so that it is closed. That is, because the warmup control is exerted and, at the same time, the exhaust opening is closed by the exhaust-window operation mechanism 4, the heat of the heater is not released out of the exhaust opening, and this improves efficiency of heating the fixing device and shortens warmup time.
